This application is a national phase entry under 35 U.S.C. 371 from International Application No. PCT/US01/43357, filed 20 Nov. 2001, which claims priority benefit from U.S. Provisional Application No. 60/250,678, filed 01 Dec. 2000, U.S. Provisional Application No. 60/273,469, filed 05 Mar. 2001, and U.S. Provisional Application No. 60/284,616, filed 18 Apr. 2001.

FIELD OF THE INVENTION

This, invention relates to certain pyrazoles and pyrazolines, their N-oxides, agriculturally suitable salts and compositions, and methods of their use for controlling undesired vegetation.

BACKGROUND OF THE INVENTION

The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybean, sugar beet, corn (maize), potato, wheat, barley, tomato and plantation crops, among others, is very desirable. Uncontrolled weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of undesired vegetation in noncrop areas is also important. For example, many products are commercially available for these purposes, but the need continues for new compounds that are more effective, less costly, less toxic, environmentally safer or have different modes of action.

DETAILS OF THE INVENTION

In the above recitations the term “alkyl”, used either alone or in compound words such as “alkylthio” or “haloalkyl” includes straight-chain or branched alkyl, such as, methyl, ethyl, n-propyl, i-propyl, or the different butyl, pentyl or hexyl isomers. The term “1–2 alkyl” indicates that one or two of the available positions for that substituent may be alkyl. “Alkenyl” includes straight-chain or branched alkenes such as 1-propenyl, 2-propenyl, and the different butenyl, pentenyl and hexenyl isomers. “Alkenyl” also includes polyenes such as 1,2-propadienyl and 2,4-hexadienyl. “Alkynyl” includes straight-chain or branched alkynes such as 1-propynyl, 2-propynyl and the different butynyl, pentynyl and hexynyl isomers. “Alkynyl” can also include moieties comprised of multiple triple bonds such as 2,5-hexadiynyl. “Alkoxy” includes, for example, methoxy, ethoxy, n-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers. “Alkoxyalkyl” denotes alkoxy substitution on alkyl. Examples of “alkoxyalkyl” include CH₃OCH₂, IH₃OCH₂CH₂, CH₃CH₂OCH₂, CH₃CH₂CH₂CH₂OCH₂ and CH₃CH₂OCH₂CH₂. “Alkylthio” includes branched or straight-chain alkylthio moieties such as methylthio, ethylthio, and the different propylthio, butylthio, pentylthio and hexylthio isomers. “Cycloalkyl” includes, for example, cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. “Saturated Carbocyclic” ring denotes a ring having a backbone consisting of carbon atoms linked to one another by single bonds; unless otherwise specified, the remaining carbon valences are occupied by hydrogen atoms.

The term “halogen”, either alone or in compound words such as “haloalkyl”, includes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as “haloalkyl”, said alkyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of “haloalkyl” include F₃C, ClCH₂, CF₃CH₂ and CF₃CCl₂. The terms “haloalkenyl”, “haloalkynyl”, “haloalkoxy”, and the like, are defined analogously to the term “haloalkyl”. Examples of “haloalkenyl” include (Cl)₂C═CHCH₂ and CF₃CH₂CH═CHCH₂. Examples of “haloalkynyl” include HC≡CCHCl, CF₃C≡C, CCl₃C≡C and FCH₂C≡CCH₂. Examples of “haloalkoxy” include CF₃O, CCl₃CH₂O, HCF₂CH₂CH₂O and CF₃CH₂O

The total number of carbon atoms in a substituent group is indicated by the “C_(i)–C_(j)” prefix where i and j are numbers from 1 to 12. For example, C₁–C₃ alkylsulfonyl designates methylsulfonyl through propylsulfonyl; C₂ alkoxyalkyl designates CH₃OCH₂; C₃ alkoxy-alkyl designates, for example, CH₃CH(OCH₃), CH₃OCH₂CH₂ or CH₃CH₂OCH₂; and C₄ alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH₃CH₂CH₂OCH₂ and CH₃CH₂OCH₂CH₂. In the above recitations, when a compound of Formula 1 contains a heterocyclic ring, all substituents are attached to this ring through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

When a group contains a substituent which can be hydrogen, for example R³, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted. When a variable group is shown to be optionally attached to a position, for example (R¹⁵)_(p)1 wherein p¹ may be 0, then hydrogen may be at the position even if not recited in the variable group definition. When a position on a group is said to be “not substituted” or “unsubstituted”, then hydrogen atoms are attached to take up any free valency.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the present invention comprises compounds selected from Formula 1, N-oxides and agriculturally suitable salts thereof. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form.

According to commonly accepted definition, the terms “aryl” and “aryl ring” denote a phenyl or benzene ring subject to optional substitution. The term “carbocyclic ring” denotes a ring wherein the atoms forming the ring backbone are selected only from carbon. The term “heteroaromatic ring” denotes a heterocyclic ring wherein each of the ring atoms is essentially in the same plane and has a p-orbital perpendicular to the ring plane, and in which (4n+2) π electrons, where n is 0 or a positive integer, are associated with the ring to comply with Hückel's Rule. The term “heterocyclic ring” denotes a ring wherein the atoms forming the ring backbone are selected from not only carbon but also heteroatoms such as oxygen, sulfur and nitrogen. For sake of illustration, heteroaromatic rings include, but are not limited to, furan, thiophene, pyrrole, pyrazole, imidazole, oxazole, thiazole, isoxazole, isothiazole, pyridine, pyridazine, pyrimidine, pyrazine and 1,3,5-triazine. The heterocyclic ring can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

The aryl or heteroaromatic ring of radical A of Formula 1 is optionally substituted by one or more substituents selected from halogen, cyano, C₁–C₆ alkyl, C₁–C₄ haloalkyl, C₂–C₆ alkenyl, C₂–C₆ alkynyl, OR⁸, —S(O)_(k)R⁹, —C(O)R¹⁰, —C(O)OR¹¹ and —C(O)NR¹²R¹³. Furthermore for the purpose of defining the scope of the invention, by removing in effect one hydrogen radical from each of two substituent groups, the groups may be combined to form a saturated or partially saturated 5 or 6-membered ring fused to the aforementioned aryl or heteroaromatic ring, and said fused ring system is optionally substituted with one or more R⁷. For example, removing one hydrogen from each methyl of A-14 allows combination to form the fused dihydrofuran ring of A-56.

One skilled in the art will appreciate that not all nitrogen-containing heterocycles can form N-oxides, as oxidation to the oxide requires an available lone electron pair on the nitrogen atom; one skilled in the art will recognize those nitrogen-containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748–750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18–19, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M. R. Grimmett and B. R. T. Keene in Advances in Heterocyclic Chemistry, vol. 43, pp 139–151, A. R. Katritzky, Ed., Academic Press; M. Tisler and B.

Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390–392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.

Compounds of the Formula 1 can be readily prepared by one skilled in the art by using the reactions and techniques described in Scheme 1 to Scheme 4 below. In cases where a substituent of the starting material is not compatible with the reaction conditions described for any of the reaction schemes, the substituent can be converted to a protected form prior to the described reaction scheme and then deprotected after the reaction using commonly accepted protection/deprotection techniques (see Green, T. W and Wuts, P. G., Protecting Groups in Organic Transformations, 3rd Edition, John Wiley and Sons, New York, 1999). Otherwise, alternative approaches known to one skilled in the art are available. The definitions of A, R¹, R^(2a), R^(2b), W, Y, and Z in compounds of Formulae 1–4 below are as defined in the Summary of the Invention.

As shown in Scheme 1, a compound of Formula 1 wherein Y is O can be prepared by contacting a compound of Formula 2 with 1–2 molar equivalents of a compound of Formula 3 in the presence of 1–1.5 molar equivalents of a dialkyl azodicarboxylate such as diethyl azodicarboxylate and 1–2 molar equivalents of a triarylphosphine such as triphenylphosphine.

The reaction is carried out in an inert solvent such as diethyl ether, tetrahydrofuran, methylene chloride, toluene or xylene at temperatures between −20 and 110° C., and preferably from −10° C. to ambient temperatures. The reaction time ranges from 1 hour to 4 days. The compound of Formula 1 is isolated using conventional purification methods such as extraction, concentration, chromatography and crystallization.

As shown in Scheme 2, a compound of Formula 1 wherein Y is O and Z is O or S can also be prepared by contacting a compound of Formula 2 wherein Z is O or S with a mixture prepared by mixing 1–2.5 molar equivalents of a compound of Formula 3, 1–2.5 molar equivalents of thionyl chloride and 2–5 molar equivalents of diisopropylethylamine in an inert solvent such as methylene chloride, tetrahydrofuran, diethyl ether, toluene or xylene.

The reaction is carried out at temperatures between −20 and 110° C. and preferably from 0° C. to ambient temperature. The reaction time ranges from 1 hour to 5 days. The compound of Formula 1 is isolated using conventional purification methods.

Alternatively as shown in Scheme 3, a compound of Formula 1 wherein Y is O is prepared by contacting a compound of Formula 4 with a compound of Formula 3 in the presence of a base such as N,N-diisopropylethylamine, NaH or KOC(CH₃)₃ or an excess of the compound of Formula 3.

The reaction is carried out by adding 1 molar equivalent of a compound of Formula 4 to a mixture of 1–2.5 molar equivalents of a compound of Formula 3 in an inert solvent such as diethyl ether, tetrahydrofuran, methylene chloride, NN-dimethylformamide or toluene under N₂ at ambient temperature. When less than about 2 molar equivalents of the Formula 3 compound is used, then about 0.5–2.5 molar equivalents of an additional base such as N,N-diisopropylethylamine, NaH or KOC(CH₃)₃ is optionally included in the Formula 3 mixture before addition of the Formula 4 compound. After the addition, the reaction mixture is stirred at temperatures between about −20 to 110° C., and preferably from about −10° C. to around 90° C. for a period of time ranging from 1 hour to 4 days. The reaction mixture is then poured into an excess amount of water and the aqueous layer is extracted with ethyl acetate between one to three times. The organic layers are separated from the aqueous layers, then combined and dried over a drying agent such as MgSO₄ or Na₂SO₄ and subsequently concentrated. The residue is purified by conventional techniques such as column chromatography over silica gel with eluents such as solutions of ethyl acetate and hexanes in various ratios or solutions of methylene chloride and hexanes in various ratios to give the desired compounds of Formula 1 wherein Y is O.

As shown in Scheme 4, a compound of Formula 1 wherein Y is S is prepared by treating a compound of Formula 1 wherein Y is O with Lawesson's Reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide) or P₂S₅ using methods or slight modification thereof taught in: Heterocycles 1995, 40(1), 271–8; J.

Step C: Preparation of 3-(5,6-dihydro-4,4-dimethyl-2(4B)-cyclopentapyrazolyl)-1-[3-(trifluoromethyl)phenyl]-2-pyrrolidinone

To a solution of 2,4,5,6-tetrahydro-6,6-dimethylcyclopentapyrazole (0.41 g with 60% purity, 1.8 mmol) in N,N-dimethylformamide (20 mL) under nitrogen at room temperature was added sodium hydride (60% in mineral oil, 86 mg, 2.16 mmol). The mixture was stirred at room temperature under nitrogen for ˜15 minutes, and then 3-hydroxy-1-[3-(trifluoromethyl)phenyl]-2-pyrrolidinone methanesulfonate (0.5 g, 1.8 mmol) was added. The resulting reaction mixture was stirred at room temperature for 72 hours. The reaction mixture was then poured into water (˜100 mL) and the aqueous layer extracted with ethyl acetate (2×30 mL; brine solution was added to separate the layers). The organic extracts were combined and concentrated to give a crude product. This crude product was further purified by column chromatography (silica gel, ˜20% ethyl acetate/˜80% hexanes) to give the title compound, a compound of this invention, as an oil, which on standing crystallized to provide a solid (69 mg) melting at 123–126° C.

Compounds of this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible (“wettable”) or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or “overcoated”). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Weight Percent Active Ingredient Diluent Surfactant Water-Dispersible and Water-   5–90  0–94 1–15 soluble Granules, Tablets and Powders. Suspensions, Emulsions,   5–50 40–95 0–15 Solutions (including Emulsifiable Concentrates) Dusts   1–25 70–99 0–5 Granules and Pellets 0.01–99  5–99.99 0–15 High Strength Compositions   90–99  0–10 0–2

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, N.J. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, N.J., as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.

Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrolidone, ethylene glycol, polypropylene glycol, propylene carbonate, dibasic esters, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol, benzyl and tetrahydrofurfuryl alcohol.

Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling, see, for example, U.S. Pat. No. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, “Agglomeration”, Chemical Engineering, Dec. 4, 1967, pp 147–48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8–57 and following, and World Patent Publication 91/13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. Pat. No. 4,144,050, U.S. Pat. No. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. Pat. No. 5,180,587, U.S. Pat. No. 5,232,701 and U.S. Pat. No. 5,208,030.

Test results indicate that the compounds of the present invention are highly active preemergent and postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, air fields, river banks, irrigation and other waterways, around billboards and highway and railroad structures. Many of the compounds of this invention, by virtue of selective metabolism in crops versus weeds, or by selective activity at the locus of physiological inhibition in crops and weeds, or by selective placement on or within the environment of a mixture of crops and weeds, are useful for the selective control of grass and broadleaf weeds within a crop/weed mixture. One skilled in the art will recognize that the preferred combination of these selectivity factors within a compound or group of compounds can readily be determined by performing routine biological and/or biochemical assays. Compounds of this invention may show tolerance to important agronomic crops including, but is not limited to, alfalfa, barley, cotton, wheat, rape, sugar beets, corn (maize), sorghum, soybeans, rice, oats, peanuts, vegetables, tomato, potato, perennial plantation crops including coffee, cocoa, oil palm, rubber, sugarcane, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple, hops, tea and forests such as eucalyptus and conifers (e.g., loblolly pine), and turf species (e.g., Kentucky bluegrass, St. Augustine grass, Kentucky fescue and Bermuda grass). Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growth.

As the compounds of the invention have both preemergent and postemergent herbicidal activity, to control undesired vegetation by killing or injuring the vegetation or reducing its growth, the compounds can be usefully applied by a variety of methods involving contacting a herbicidally effective amount of a compound of the invention, or a composition comprising said compound and at least one of a surfactant, a solid diluent or a liquid diluent, to the foliage or other part of the undesired vegetation or to the environment of the undesired vegetation such as the soil or water in which the undesired vegetation is growing or which surrounds the seed or other propagule of the undesired vegetation.

A herbicidally effective amount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of compounds of this invention is about 0.001 to about 20 kg/ha with a preferred range of about 0.004 to about 1.0 kg/ha One skilled in the art can easily determine the herbicidally effective amount necessary for the desired level of weed control.

Compounds of this invention, properly formulated for application onto agricultural land or crops, are especially useful for prevention of weed growth in cultivated rice crops such as flooded paddy rice or dryland seeded or upland rice. These general groupings of rice crop cultivation methods include transplanted (i.e. transplanted into a flooded field (paddy)), water-seeded (i.e. seeded onto a flooded field so the seeds are positioned at or near the soil surface), broadcast dry-seeded (i.e. seeded onto the surface of the soil (typically prepared by cultivation) of a dry field, which is then flooded), and dry soil planted (i.e. seeded into the soil (so that the soil covers the seeds) of a dry field) with flood (i.e. the field is subsequently flooded) or without flood (i.e. the field is not subsequently flooded, and the rice crop relies instead on natural rainfall or non-flood irrigation).

The formulated compounds of the invention can be applied (i.e. contacted to the weeds or their environment) using a variety of methods, timings, or their combination(s), which allow the user to choose that which is most appropriate for the particular rice culture. The compounds can be applied: to soil or flood waters before transplants or seed are planted; at time of transplanting or seed planting; after transplanting or seed planting; after seed planting but before crop and/or weeds emerge; or after planting and the crop and/or weeds have emerged. The compounds can be applied, for example, as a treatment spray mixture, mixed with solid fertilizer or alone, or included in irrigation water. Applications to the soil can be enhanced by shallow mixing of the compounds into the soil with tillage equipment. The compound(s), alone or in mixture, can be applied directly to flood waters of the paddy as a liquid spray, suspension concentrate, or prepared granule or dispersible solid. The compounds can be applied over the top of the rice crop to emerged weed foliage and flood waters, or as a granule that can be broadcast-distributed onto the soil surface or into the flood, or they can incorporated in the soil before planting.

Applications of the compounds of the invention can be timed to coincide with specific stages of weed and/or crop growth dependent upon the rice culture practiced. The compounds can be applied to soil or flood waters: before crops are planted, at time of planting, after the crop is planted but before emergence, or after the crop emerges.

The compounds can be applied to the paddy by various means including, but not limited to: introduction or injection at the water source; manual or mechanical-equipment aided distribution from within or upon the levees; and dispersal or delivery by boat, airplane or helicopter.

Compounds of this invention, properly formulated for application onto agricultural land or crops, are also especially useful for prevention of weed growth in nonflooded crops such as maize when applied to the soil before weeds emerge or shortly after their emergence, either before or after the crop emerges. Applications to the soil can be made before, during, or after planting, and can be enhanced by shallow mixing of the compounds into the soil with tillage equipment. The formulated compounds can be applied to the soil, for example, as a treatment spray mixture, mixed with solid fertilizer or included in irrigation water.

Compounds of this invention can be used alone or in combination with other commercial herbicides, insecticides and fungicides, and other agricultural chemicals such as fertilizers. Compounds of this invention can also be used in combination with commercial herbicide safeners such as benoxacor, dichlormid and furilazole to increase safety to certain crops. Mixtures of the compounds of the invention with other herbicides can broaden the spectrum of activity against additional weed species, and suppress the proliferation of any resistant biotypes.

Particularly preferred are mixtures of Index Table A Compound 1 with daimuron and mixtures of Index Table A Compound 1 with quinoclamine.

The following Tests demonstrate the control efficacy of the compounds of this invention against specific weeds. The weed control afforded by the compounds is not limited, however, to these species. See Index Tables A1 to B for compound descriptions. The abbreviation “Ex.” stands for “Example” and is followed by a number indicating in which example the compound is prepared.

Seeds of barnyardgrass (Echinochloa crus-galli), crabgrass (Digitaria spp.), giant foxtail (Setaria viridis), morning glory (Ipomoea spp.), redroot pigweed (Amaranthus retroflexus) and velvetleaf (Abutilon theophrasti) were planted into a sandy loam soil and treated preemergence by soil drench with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant. At the same time, these crop and weed species were also treated postemergence sprayed to runoff with test chemicals formulated in the same manner.

Plants ranged in height from two to eighteen cm and were in the one- to two-leaf stage for the postemergence treatment. Treated plants and untreated controls were maintained in a greenhouse for approximately eleven days, after which time all treated plants were compared to untreated controls and visually evaluated for injury. Plant response ratings, summarized in Table A, are based on a 0 to 10 scale where 0 is no effect and 10 is complete control. A dash (-) response means no test results.

Seeds selected from barnyardgrass (Echinochloa crus-galli), Surinam grass (Brachiaria decumbens), cocklebur (Xanthium strumarium), corn (Zea mays), crabgrass (Digitaria sanguinalis), giant foxtail (Setaria faberii), lambsquarters (Chenopodium album), morning glory (Ipomoea hederacea), pigweed (Amaranthus retroflexus), rice (Oryza saliva) and velvetleaf (Abutilon theophrasti) were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant.

At the same time, plants selected from these crop and weed species and also blackgrass (Alopecurus myosuroides), wheat (Triticum aestivum) and wild oat (Avena fatua) were treated with postemergence applications of test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments. Plant species in the flooded paddy test consisted of rice (Oryza saliva), smallflower flatsedge (Cyperus difformis), duck salad (Heteranthera limosa) and barnyardgrass (Echinochloa crus-galli) grown to the 2-leaf stage for testing. Treated plants and controls were maintained in a greenhouse for 13 to 15 days, after which time all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table B, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

Seeds of plant species selected from bermudagrass (Cynodon dactylon), Surinam grass (Brachiaria decumbens), cocklebur (Xanthium strumarium), corn (Zea mays), crabgrass (Digitaria sanguinalis), woolly cupgrass (Eriochloa villosa), giant foxtail (Setaria faberii), goosegrass (Eleusine indica), johnsongrass (Sorghum halepense), kochia (Kochia scoparia), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), yellow nutsedge (Cyperus esculentus), pigweed (Amaranthus retroflexus), common ragweed (Ambrosia elatior), soybean (Glycine max) and velvetleaf (Abutilon theophrasti) were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant.

At the same time, plants selected from these crop and weed species and also winter barley (Hordeum vulgare), blackgrass (Alopecurus myosuroides), canary grass (Phalaris minor), chickweed (Stellaria media), downy brome (Bromus tectorum), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum), wheat (Triticum aestivum), wild oat (Avena fatua) and windgrass (Apera spica-venti) were treated with postemergence applications of some of the test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments. Plant species in the flooded paddy test consisted of rice (Oryza saliva), smallflower flatsedge (Cyperus difformis), duck salad (Heteranthera limosa) and barnyardgrass (Echinochloa crus-galli) grown to the 2-leaf stage for testing. Treated plants and controls were maintained in a greenhouse for 12 to 14 days, after which time all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table C, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

Four plastic pots (ca. 16-cm diameter) per rate were partially filled with sterilized Tama silt loam soil comprised of a 35:50:15 ratio of sand, silt and clay and 2.6% organic matter. Separate plantings for each of the four pots were as follows. Seeds from the U.S. of Heteranthera limosa (Hl), Monochoria vaginalis (Mv), Ammania auriculata (Aa), and Sphenoclea zeylanica (Sz) were planted into one 16-cm pot for each rate. Seeds from the U.S. of Cyperus iria (Ci), Leptochloa fascicularis (Li), one stand of 9 or 10 direct-seeded rice seedlings (Oryza saliva cv. ‘Japonica—M202’; Oss), and one stand of 6 transplanted rice seedlings (Oryza sativa cv. ‘Japonica—M202’; Ost) were planted into one 16-cm pot for each rate. Seeds from the U.S. of Cyperus difformis (Cd), Alisma plantago-aquatica (Ap), and Scirpus mucronatus (Sm) were planted into one 16-cm pot for each rate. Seeds from the U.S. of Echinochloa crus-galli (Ecg), Echinochloa oryzicola (Eor), Echinochloa oryzoides (Eoz) and Echinochloa colonum (Ecc) were planted into one 16-cm pot for each rate. Plantings were sequential so that crop and weed species were at the 2.0 to 2.5-leaf stage at time of treatment.

Potted plants were grown in a greenhouse with day/night temperature settings of 29.5/26.7° C., and supplemental balanced lighting was provided to maintain a 16-hour photoperiod. Test pots were maintained in the greenhouse until test completion.

Chemical treatments consisting of Compound 1 of Index Table A (Cmpd 1), daimuron (Cmpd D), quinoclamine (Cmpd Q) and combinations thereof were formulated in acetone. At time of treatment, test pots were flooded to 3 cm above the soil surface, treated by application of test compounds directly to the paddy water, and then maintained at that water depth for the duration of the test. Effects of treatments on rice and weeds were visually evaluated by comparison to untreated controls after 21 days. Plant response ratings are reported on a 0 to 100 scale; where 0 is no effect and 100 is complete control. ND means no data.

Colby's equation was used to calculate the expected additive herbicidal effect of the mixtures of Compound 1 with daimuron (Cmpd D) and quinoclamine (Cmpd Q). Colby's equation (Colby, S. R “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations,” Weeds, 15(1), pp 20–22 (1967)) calculates the expected additive effect of herbicidal mixtures, and for two active ingredients is of the form: P _(a+b) =P _(a) +P _(b)−(P _(a) P _(b)/100) wherein P_(a+b) is the percentage effect of the mixture expected from additive contribution of the individual components,

-   -   P_(a) is the observed percentage effect of the first active         ingredient at the same use rate as in the mixture, and     -   P_(b) is the observed percentage effect of the second active         ingredient at the same use rate as in the mixture.

Plant response ratings and additive effects expected from the Colby Equation are shown in Table D.

As can be seen from the results listed in Table C for this test, mixtures of daimuron and quinoclamine with Compound 1 reduced phytotoxicity on direct-seeded rice (Oss), daimuron being more effective than quinoclamine in this regard. In contrast to the safening on rice, these combinations generally retain excellent effect for controlling weeds. The results suggest some synergism of mixtures of Compound 1 with daimuron on Ammania auniculata (Aa) and mixtures of Compound 1 with quinoclamine on Ammania auriculata (Aa) and Scirpus mucronatus (Sm). Mixtures of Compound 1 with daimuron showed synergism on all four Echinochloa species, E. crus-galli (Ecg), E. oryzicola (Eor), E. oryzoides (Eoz) and E. colonum (Ecc), while mixtures of Compound 1 with quinoclamine show synergism on two species, E. crus-galli (Ecg) and E. oryzoides (Eoz). The synergism on Echinochloa species with safening on direct-seeded rice is particularly surprising, as both Echinochloa species and rice are grasses.
